Research

Multimodal Sensing

An ideal soft sensory device should detect multiple stimuli—such as strain, pressure, and temperature—and differentiate between them, much like human skin. My research focuses on developing soft multimodal sensors with stimuli-decoupling capabilities. By designing subsensors selectively sensitive to target stimuli while remaining unaffected by others, and by integrating these subsensors into a single device, I aim to advance more comprehensive soft sensors for electronic skin (e-skin) applications.


Broadband Mechano-Acoustic Sensing

While most soft sensors developed to date can effectively detect quasi-static mechanical stimuli such as strain and pressure, they often show reduced performance—or even complete insensitivity—at higher frequencies, sometimes as low as a few tens of hertz. This limitation poses a significant challenge, as many vital physiological signals—such as pulse (1–1.5 Hz), heart sounds (10–250 Hz), voice (150–350 Hz), lung sounds (100–2000 Hz), and coughs (500–2500 Hz)—manifest as mechano-acoustic vibrations spanning a broad frequency range. To bridge this gap, I aim to develop soft sensors that combine high sensitivity to both subtle mechanical deformations and rapid, dynamic stimuli. By leveraging optimized device architectures and efficient transduction mechanisms, this work targets broadband mechano-acoustic sensing, enabling comprehensive monitoring across biomedical and human-machine interface applications.
